Hi JT, welcome aboard.
This is a concern with operations for which the ops eng support either has no operational experience or, alternatively, doesn't have a very close relationship with the flight ops organisation.
I think you can assume this is the situation.
That said, Flt Ops seems to me to be amazingly apathetic to the risk.
Perhaps it is indeed that an alternative to the valley route would penalise RTOW and nobody wants to open that can of worms.
